편측 과두 흡수로 인한 교합붕괴 환자의 턱관절 치환술을 동반한 교정 치험례

Abstract

This case report presents the interdisciplinary management of a patient with occlusal collapse resulting from unilateral condylar resorption. The patient presented with facial asymmetry, posterior bite collapse, and significant periodontal breakdown on the affected side. To restore mandibular structure and function, unilateral temporomandibular joint (TMJ) replacement was performed. After confirming periodontal stability through comprehensive periodontal therapy, orthodontic treatment was initiated to upright the severely inclined dentition and close residual spaces using controlled mechanics adapted to compromised periodontal support. Through this staged, multidisciplinary approach—including surgical, periodontal, and orthodontic interventions—functional occlusion, facial symmetry, and skeletal harmony were achieved, demonstrating a favorable esthetic and functional outcome with long-term prognosis.
